摘要： The invention provides a sealed package system for housing at least one medical electrode apparatus and for enabling the periodic testing thereof, comprising a thin, generally flat flexible envelope constructed and arranged to form an interior cavity for enclosing a conductive gel contact surface of an electrode apparatus, the envelope having at least one continuous layer of a homogeneous, non-conductive, polymeric material, the envelope further having first and second sides; and a structure for conducting current across the envelope to the interior cavity, the conductive structure being electrically connectible to the electrode conductive contact surface.

摘要： A defibrillation catheter having a connection from an electrode to an infeed conductor in the mid-point area of the electrode. The mid-point current feed provides for a voltage drop from the center of the electrode to its ends, which minimizes extreme electrical fields which normally develop at the electrode ends. The coil resistance is selected to further optimize the field distribution so as to allow a large passage of defibrillation current without cell damage.

摘要： Transvenous leads including an outer atrial and an inner ventricular spaced wound coils coaxial with respect to each other and including a closed fixation loop connected to the outer lead. The closed fixation loop extends outwardly at an angle with respect to the outer lead. An inner lead is slideably adjustable within the outer lead and supports a ventricular electrode. The outer lead supports an atrial electrode. A connector at the other end of the leads supports and secures a connector pin for the outer lead in one sleeve and provides for slideable adjustment of the inner lead which includes a proximal tip in the other sleeve. An O-ring engages in an O-ring groove in the other sleeve to provide a liquid seal between the atrial coil and the end of the ventricular coil. The proximal tip and connector pin connect to a pulse generator. The transvenous leads with the closed fixation loop are intended for pacing the ventricular and atrial chambers of a heart.
